This male may belong to the same species as the photo above. The colors and markings, as well as the thicker front legs, are probably used for courtship and for male-male threat displays.

Menemerus bivittatus is a native of Africa and has been introduced into many other parts of the world. It is very commonly found on the walls of buildings.

Why is one eye black and the other green? Unlike us humans, jumping spiders can’t rotate their eyes, because the lenses are a fixed part of the exoskeleton. However, jumping spiders can scan their visual field, but they do it in a very interesting way. Their retinas can move from side-to-side (see link below). In this photo, the retina of the left eye is visible. This video and also this video show the retinas moving.
